Shoe static outsole structrue connected to rotary midsole structrue

ABSTRACT

Shoes which by their construction avoid twisting stress which save especially the knees of humans and lower legs of horses from serious injury are shoes which are equipped with “Turn-Table” topped outsold disc treads of simple anti-friction design upon which top surface said shoes can rotate on to any 360 degree direction while said outsole bottom surface tread is frictionally adhered to a footing surface with said shoe outsole discs that resist any linear free wheeling motion or footing slippage even when said shoe is substantially tilted to a rapid action canted positional arrangement with a footing surface due to substantial disc perimeter tread flexibility.

Sir:

Be it known that John Robert Manis, whose residence is 17320 MeridianBlvd., Township of Hudson, County of Pasco, State of Florida 34667-4937and a citizen of the United States of America has invented new anduseful shoe Static Outsole Structures connection to Rotary MidsoleStructures disclosed previously in my full provisional patentapplication having 22 drawing figures filed in the United States Patentand Trademark Office on Oct. 27, 2003 given provisional patentapplication filing No.-60/514,778, and further having filed a secondnearly identical copy of the same invention in which some small errorswere corrected and which said second said full provisional applicationhad with it an identical set of twenty two drawings which were identicalto the set of 22 drawings filed with the first said provisionalapplication. The second said full provisional application received thesame filing date of Oct. 27, 2003 as the said first provisionalapplication with the said second full provisional application given thefiling No. 60/514778 and of which I prefer claiming said ProvisionalPatent application filing date thereof Oct. 27, 2003 I claim as thefiling date for this Patent Application which specification discloses nonew subject matter and pray that Letters Patent be allowed and issuedfor this said Patent Application of which the USPO had responded toearlier and dismissed the claimed filing date of the above identifiedprovisional applications filed on Oct. 27, 2003 due to the entire set of22 drawing figures not having accompanied said provisional applicationspecification they referred to numerically and of certain language alsothereto nor did my declaration as the sole inventor of said aboveidentified patent application. As to this action of the USPO I wasfurther informed that the only patent application filing date that wouldbe recognized for my above identified invention would be the date uponwhich my answer to the USPTO above action was received in the USPOwithout benefit of any advice given the pro ce applicants' right torespond Therefore I would respectfully say that I the pro ce inventordid all of the work of first envisioning the invention and then everybit of all of the work of drafting all of the drawings and all of thelanguage of the specification, and all claims first informally and thenformally for filing in the USPTO having brought the full patentapplication myself to my little rural USPS building where in my rush toget the application out into the mails for that day which was mydeadline day for filing my application to receiving the filing date ofmy said provisional applications I wanted to be absolutely sure that Ihad inserted all of the necessary papers of my patent application intomy mailing envelope and therefore I asked the Postmaster Joseph LaFrancaat the counter of the Aripeka, Fla. Post Office branch 727-868-6876 togive me a few moments to take out all of my patent applications' papersto make sure all necessary papers were in my mailing envelope which thesaid postmaster allowed time to do and after seeing that all saidapplication papers were present and in order I put them all back into mymailing envelope but which now I could not get the envelopes' adhesivecoated flap to seal closed at which time I requested that the postmastersend my envelope to the USPTO via Overnight Express Mail. At which timethe postmaster said that I need not worry that my original mailingenvelop would not seal because he was going to put my said envelop intoa separate very strong Express Mail Envelope then calculated my postagewhich I paid and received a receipt for and left the Post Officebuilding while Postmaster Joseph Lafranca was still in the process ofputting my unsealed patent application mailing envelope into the saidother overnight Express Mail Envelope. Later when I received a responsefrom the USPTO that the said application was received at the USPTOwithout the applications required drawings and with other requireddocuments missing also On those grounds the USPTO denied my right toclaim the filing date of the said patents' earlier filed saidprovisional application and and informed me that I would not receive afiling date for my patent until all necessary drawings were properlyfiled in the USPTO and payment of all USPO fees were paid but then Iwould not receive my earlier filed provisional applications' filing datebut just a leter date at the time said drawing were received and saidfees paid which actually would not benefit me any more than more simplyrefiling said regular patent application. Not understanding how it waspossible that my said patent application drawings which I double checkedon and saw and mailed at the said Aripeka Post Office had not beenreceived by the USPTO Therefore I went back to said post office andinformed Postmaster Joseph Lafranka of the notice from the USPTO ofmissing drawings and other papers from my said application he mailed forme that arrived at the USPTO. The postmaster then said that he didrecall that I had inspected all of my said patent application papers tomake sure all necessary parts were there ready for mailing including thedrawings of which I am sure as the postmaster admitted the to being onlya foot away from the applicant when he checked out the applicationpapers directly in front of him got a good glimpse of the 22 patentdrawing figues I had spread out as just mentioned directly in front ofhim and so therefore I asked the Postmaster if he would kindly write anote for me to give to the USPTO that he the postmaster had witnessedthat the applicant had made said inspection of his patent applicationbefore mailing it which the postmaster did write in said note and gaveit to the applicant of which a copy of said note is attached to thispresent substitute now double spaced application which has no newsubject matter I had earlier sent as aforementioned. I am 73 year oldand not in the best of health having gotten over and still recoveringfrom a number of illnesses including a urinal bladder infection whichhave caused unavoidable delays in getting all of this various legalpaperwork for the USPTO in proper order as a pro se applicant who has noone to turn to who is knowledgeable for help in these matter and wishesthat the USPTO will change its position and allow the applicant thefiling date of his earlier filed provisional patent application for hisidentical present regular patent application which the applicant praysfor an early decision on this matter because of the applicants missingdrawings and the possibility of someone not the inventor attempting tofile a patent application from unique information that may be seen byanyone carefully inspecting my lost patent drawings which have been lostnow for quite a long time. Therefore I respectfully request PTOassistance in the filing and prosecution of this my pro se applicationfor letters patent

FIELD OF THE INVENTION

The invention relates to shoes, and more particularly to shoe solesconstruction.

BACKGROUND OF THE INVENTION

There have been many advances made in designing cushioned “non-slip”outsole structures to make sure that a shoe will not slip on a footingsurface especially with sport shoe design. But what has not beenrealized with these said advances is that by increasing greaterfrictional adhesiveness traction for a shoe's outsole greater becomesthe force and physical stress of a shoe wearer to break free said shoe'soutsole from a footing surface, gravitated to, especially when said shoewearer must make an in place shoe turn with one shoe with the fallweight of said shoe wearer gravitating down on said shoe's “non-slip”outsole. Shoes generally right up to present times do not provide forsubstantial free turning of a shoe when the weight of said shoe wearersbody causes said “non-slip’ outsole to be frictionally adhered to afooting surface, especially as concerns the forefoot region leverage ofsaid outsole. And although there have been advances in the constructionquality and function of the insole, and outsole; quality advances havenot been developed to allow the upper shoe to operate correctly to turneither clockwise or counter clockwise to any point of 360 degrees whilesaid shoe's outsole remains frictionally adhered in one position at afooting surface by the weight of the shoe wearer Also prior art does notshow development of increasing footing surface contact of a shoe'scanted outsole position which said outsole has only a small outer edgessurface remaining in contact to a footing surface which then often failsto prevent slippage for a shoe wearer.

What is true within the discourse of the above specification as concernsphysically stressful human activity caused by said shoes; is also truefor certain domestic animals when these animals are forced to walk uponunnatural man made surfaces such as rough concrete with footgear notfolly developed to enable an animal to do so safely as is exemplified inthis specification concerning horse's horseshoes designed to have“proper” traction which can become snagged to certain man made surfacesand cause twisting stress injuries of a horse's leg tendons andligaments. It is known that horses often are suddenly excited into afrenzy of sudden physical activity in resistance to being handled bytheir human caretakers. And when these exacerbated excited leg movementsoccur on man made surfaces such as on hard rough non-slip concretesurfaces that are common surfaces for the floors of horse stables; thenthese said sudden leg movements are apt to strain the horse's legs viathe turning resistance of a horse's hoofs on horseshoes which often snagon such said rough surfaces of concrete floors and also on other manmade surfaces. Such stressful horse activity, especially when repeatedover and over again often causes leg injuries which recognizance of thesource of is seldom recognized by horse owners and horse handlers.

The applicant has studied movies of movements of horses and researchedthe diagnostic protocol for degenerative suspensory ligament desmitisDLSD of horses lower legs. A disease found in all breeds of horses.Accept for one breed, DSLD almost always occurs in BOTH HIND LEGS of ahorse NEVER IN JUST ONE bind LEG and almost never to the front legs. Thecause of this wide spread disease is not really known, only speculatedand theorized on by veterinarians.

After conducting research on the subject in length the applicant hascome to a philosophical view of at least one cause of this disease inall breeds of horses and which applicant feels is likely to be theprinciple cause. The ligament and tendon connections to the bones andmuscles of the hone's lower legs which keep the joints of bones andmuscles in place are strong and resilient when working healthfully innormal ways with the muscles to work the normal joint action of thebones; but work the hardest when in an unhealthful manner resistabnormal twist forces occurring to the legs of the horse. The bonejoints of the lower leg of the horse are held very strongly together byligaments and tendons to resist said twisting forces to keep such bonesas the small navicular bone in place which the muscles and joints of thehorse's legs are designed by natures to be able to work to do so to onlya ceratin very limited degree without strain when resisting diagonaltwisting forces acting on the anatomy of said legs.

The applicant in viewing movements of horses has noticed on everyoccasion that when a horse is forced by a rider or ground handler tomake abnormally sharp turns with its front legs, and even with not sosharp turns, each of the horses hind leg hoofs of the horse remain inplace on a footing surface twisting around sliding in place to followthe pulling direction of the stepping front legs of the horse pullingits body around into said turn. This is a very abnormal movement for ahorse to take and occurs only when the horse is being handled to do so.As seen in rodeo horse actions, the hind legs will stay in place thisway even when a horse is forced to thrust Bill strength into tightbarrel turns sometimes with the hone's front legs jumping the front bodywildly high into such turns which fortunately occurs on the natural softsurface of mother oath but nevertheless it can be seen that the rearlegs are much more highly stressed by twisting forces occurring at thehind hoofs than are the front legs of the horse at its front hoofs whichare almost always raised off of a rooting surface one at time instepping motions to initiate and move into said such tight turningmovements, while, as mentioned, the rear hoofs usually remain in theiroriginal standing positions on said footing surface upon initiation ofsaid turns in order to Billy support the hone by simply twisting aroundwith hind feet hoofs in place into rotational sliding motions on saidfooting surface. And there is a lot of evidence that horses lower legsare not very sensitive to pain and therefor can be stressed quite oftenbut the horse not reacting stressfully when forced to make such turnswhich the applicant believes, along with shod hoof snagging to be theprinciple causes of DS

SUMMARY OF THE INVENTION

It is with these problems in mind that the applicant's invention wasdeveloped. The invention may be characterized as a shoe soleconstriction comprising a midsole layer, an outsole layer andoutsole/sole disk part including an intermediate region attached to saidmidsole and outsold/sole disk parts comprising a sole disk installationstructure part upon which an upper shoe is attached to has the potentialto rotate upon disposed immediately above and attached rotationally tosaid outsole/sole disk part when said outsole/sole disk part is at astatic positional arrangement on a toting surface and to said rotationalsole disk Installation structure. A sole disk installation structure maybe comprised of a resiliently flexible hollow outer shell wall definingan interior chamber The said shell may also be comprised of athermoplastic elastomer or composite graphite materials and said shellhaving a circular opening to which perimeter of said opening the saidoutsole/sole disk part is attached to that closes and seals saidopening. Said outsole/sole disk will herein after be referred to inremainder of the specification simply as sole disk or soledisk.

And on said sole disk pail said outer shell of said sole diskInstallation structure attached to upper shoe's midsole may rotate on.An inner filler may be encapsulated within said shell's interiorchamber. Or only said sole disk Installation structure shell'sresiliently flexible wail may function alone with its said chamber notsubstance filled nor air tight to work in resiliently flexible downwardunfolding and upward folding and canted positional reconfigurationalarrangement functions to its attached sole disk while bottom surface ofsaid sole disk is kept folly in contact to a footing surface while uppershoe remains in a canted positional arrangement to said sole disk. TheMid sole disk may have a rigid upper layer attachment structure and abottom surface integrally adhered to a bottom outsole layer of any kindof suitable configuration of softer material designed for adequatetraction to a footing surface. The said sole disk ached to said soledisk Installation structure's resiliently flexible shell chamber wallprovides cushioning from shock to the shoe when its outsole is impactingonto a footing surface by the shoe wearer even when said shoe is in acanted position to and impacting said surface.

Another embodiment of shoe sole construction of the invention comprisesfeatures where the sole disk material is resiliently flexible at andinward from the tapered region of its perimeter, and said sole disk isattached directly to a rotatable intermediate sole disk attachmentstructure of the shoe. Said resiliently flexible tapered region inwardfrom the perimeter of said sole disk remains in contact with a footingsurface when the shoe is at a canted configuration to a toting surface.

With either embodiment of shoe sole construction the midsole may extenddownward to become an outsole align between a heel sole disk and aforefoot sole disk and arranged at least one quarter inchcircumferentially rearward of a forefoot region sole disk and at leastone quarter inch circumferentially forward of a heel region sole disk.

Then “outsole” may be applied to either a heel disk sole or a forefootdisk sole and “outsole” also applied to the intermediate region betweensaid heel disk sole and said forefoot disk sole which said outsoleregion extends to the same bottom surface level as said sole disksmentioned which distinction will always be disclosed evidently withinthe discourse of the following specification. The word “shoe” asmentioned above may be applied as that which is worn by humans oranimals such as then “horseshoe” implies but the word “shoe” can also beconstrued to the meaning of the word “gear” that is used in then “animalleg gear” for the hoof or paw of an animal. The meaning of these saidterms will be apparent as they are applied either to humans or animals.

A said sole disk of any embodiment above or below may have the sole diskoutsole bottom footing surface made of a variety of materials of variousbottom configurations either in the form of a one piece solid sole diskor said outsole of said sole disk as a separate layer adhered and/orsewn to the sole disk main body and cleats or spikes may be added tosaid outsole such as cleats for said outsole of said sole disk forfootball shoes, and spikes for said outsole of sole disks for golfersshoe. Which said shoes will prevent injury and increase the agility ofthe shoe wearer.

The invention further includes an alternate embodiment to accommodatedress shoe soles made frown flat sheet stock of lather signed toaccommodate the structure of a horse's hoofs.

For the best reliable rotational functions within said embodiments ofthe invention it is preferable that portions oldie midsole, outsole andthe upper surface of disk soles upon and at which a shoe rotates aremade of internally lubricated rubber or thermoplastic elastomermaterials that have lubricating substances bound within said materialswhich do not require maintenance nor said lubricant significantly niboff onto other parts.

There are a variety of techniques to lower fiction of a rubber pan. Arubber can be formulated specifically for lower friction by usingcertain types of low friction ingredients. Coatings such as FIFE-basedcoatings, or surface treatments, such as Minnesota Rubber's F-TreatProcess, are other methods to reduce part friction.

A unique method used by Minnesota Rubber to provide fiction reduction isby the addition of lubricants into the elastomer mixture. Thesechemicals modi˜'the surface of the part to provide an “internallylubricated” compound. The presence of the lubricant does not effect thephysical properties of the rubber part. The internally lubricatedcompounds are designed for intermittent or slow cycling typeapplication. re: as applies to upper sole disks and sole diskinstallation structures and various said other parts of this inventionthat feature maintenance free lubricated parts.

It is noted here that because a sole disk and sole disk attachmentstructure allows free turning of the upper shoe without turning of saidsole disk fictionally adhered to a footing surface, said sole disk'sbottom surface wear at said footing surface should be markedly reducedwhen compared to frictional abrasive wear of the integral fixedplacement of soles of conventional shoes when the shoe wearer makesforced in place turns required to break a surface's frictional hold onthe outsole sole bottom to slide it around on said surfaces which actioncauses substantial frictional wearing of said conventional outsole.

The shoe disk soles of this invention provide linear fraction and saidshoe cm only rotate either on a heel sole disk or a forefoot sole diskwhen the shoe wearer lifts either the shoe's forefoot region or heelregion off of a footing surface therefor leaving only a heel sole diskor a forefoot sole disk on said footing surface to rotate on.

The invention also provides tractional resistance to all movement of ashoe including full resistence to linear and turning movements when saidheel and forefoot disk soles are both in contact with a footing surfacewhich therefor also includes the intermediate region of the shoe'soutsole also in contact with said footing surface between said heel andforefoot region disk soles.

OBJECTS OF THE INVENTION

The object of the invention is to construct a shoe for humans and/or foranimal hoof and paw shoe gear that allows shoes to rotate freely upon afixed position of said shoe's outsole upper surface structure while saidoutsoles's bottom surface is frictionally held to a fixed position on afooting surface by weight of the shoe wearer either at the forefootregion of the shoe with said shoe's heel and intermediate outsole areraised off said surface, or the heel region at a fixed position with thesaid shoe's forefoot region and intermediate outsole are raised off ofsaid surface. The shoe wearer is therefor able to freely rotate in placeeither on said shoe's heel region or forefoot region to any 360 degreepoint of direction, either clockwise or counterclockwise, in one and/orthe other of an upper shoe's rotatable midsole structure turning on andattached to the complemental fixed integral structure of shoe's saidoutsole of this invention held to a footing surface accomplished toreduce to a high degree twisting force stress of the ligaments andtendons of the muscles and joints of the shoe wearer being beneficial toboth humans or animals alike, especially when engaged in high stressphysical activities, and also beneficial for the infirm or elderly, andfor those recovering from foot; hoof or paw and/or leg and hip injuriesor diseases or the said shoes or animal gear may be employed for use tosimply reduce lower body stress to maintain good foot leg and hip jointhealth.

Another object is to allow shoes equipped with said sole disks of theinvention to remain to have full fractional resistance to any shoemovements when said sole disk equipped shoes heel and/or midfoot andforefoot regions remain together in frictional contact with a footingsurface.

A further object is to provide shoes with disk shaped outsoles that willallow the shoe wearer to make body turns much more quickly and with lesseffort and stress with said shoes that can make turns on said diskshaped outsoles which remain in a static footing position which actionscannot be accomplished with conventional shoes having integral outsolesfixed in place to a shoe bottom.

Another object is to employ a shoe sole in the form of a disk upon whicha shoe for humans or animal hoofed paw shoe gear can rotate on to anydesired point of 360 degrees clockwise or counterclockwise and whichsaid sole disk when brought to a canted position automatically locks inplace and will not rotate on sole disk rim flexibly maintaining asubstantial canted angular inward sole disk bottom surface contact witha footing surface.

A further object is to furnish said sole disk with a resilientlyflexible perimeter employed to maintain a substantial angularly adheredsole disk undersole surface contact to a footing surface to prevent soleslippage when a shoe is raised to most any canted configuration fromsaid footing surface.

Another object is to employ said sole disc upon which a shoe can rotateand also greatly absorb an impact force when said sole disk is movingdownward at either a tilted or full parallel configuration to a footingsurface, and which said force of impact energy is substantially absorbedaway from the foot of the shoe wearer.

A further object is to employ said sole disk in a manner by which saidsole disk can easily be removed and a replacement sole disk easilyinstalled which disk may be either identical to the said sole diskpreviously removed or the sole disk outsole surface contact region mayhave variously different shaped structures made of various kinds ofother materials to meet and serve other various activities and/orfooting surface conditions requirements of said shoe's outsole footingsurface contact structure.

Another objective is to correct and prevent the cause of most outsolewear which is caused by the conventional outsole sliding about on asurface by a shoe wearer wearing conventional shoes which have outsolesadhered at a fixed position onto the upper shoe of said shoe wearer,which said fixed outsole must overcome high frictional resistance toslide about into a turn on a surface by force of the shoe wearer's upperbody twisting about to new directions causing substantial frictionalwear to the shoe's said outsoles; which said new rotatable disk soles ofthis invention prevents and substantially reduces disk sole outsolebottom surface wear.

A particular object is to shod horses with horseshoes having features ofthis invention which allow fill and complete hoof wall flexibility.

Other objectives will be brought out or be apparent within the course ofthe following disclosure of the construction, arrangement andcombination of elements as fully described hereafter and later pointedout in the claims forming a part of the specification.

More specifically a shoe wearer can rotate ones shoes while maintaininga fixed axial positions of rotation with a fixed linear position of saidsole dislc4 which sole disk is fictionally adhesively established fixedin place at a footing surface where said shoe wearer may rotate at byweight of the shoe wearer bearing down on the non-slip undersurface ofthe said special outsoles sole disk 16 or 16A upon which said shoewearer rotates on via the shoe's rotary sole disk attachment structurerotatably connected to and on said sole disks upper surfaces 32 and 47complementarity configured to undersurface 48 end 49 of said sole diskattachment structure. Said structure 17 and 17A is held rotatable tosaid structure 16 and 16A by corresponding catch ring groove 27 andclasp ring 26. Said sole disk 16 and 16A is preferably made of fairlyresiliently flexible materials such as the elastomer materials. And thesole disk attachment structure preferably made of fairly rigidinternally lubricated materials such as ACETYL below. The alternateembodiment of a sole disk 32 and sole disk attachment structure 33 ofFIGS. 3, 7 and 10 has a sole disk preferably also made of a fairly rigidinternally lubricated plastic such as ACETYL made of components that aredimensionally stable even under extremely wet or humid conditions andwill not swell. Additionally it resists most organic solvents and iseasy to machine and does not burr easily. ACETYL is a geneticdescriptive name for two polymers: Calcine—a copolymer made byCeylonese—and DELRIN—a homopolymer made by E.L Dupont Nemours. Otherinternally lubricated plastics which are moldable may be used such aspolyamide, polysulfate polyphenylene sulfide are high-temperaturematerials which may employ graphite as a bonded self-lubricating filler.To increase ease of manufacturing another material may be used for boththe said sole disk and said sole disk attachment structuresuch—Ultrahigh-Molecular-weight Polyethylene which resists abrasion andhas a smooth, low friction surface. And often an ideal material forparts commonly made from ACETYL or PTFE materials. PTFE has anexceptionally low coefficient of fiction and high self-lubricatingcharacteristics. For use to make disk soles the said sole disk may bemade up of several layers with a top layer preferably made up of pureUltrahigh-Molecular-weight-Polyethylene or such materials, and a bottomlayer of MILLATHANE used also for the intermediate outsole of FIG. 1either homogeneously or for a combination of assembled parts. Cushioningmaterial for midsole or insole can be constructed of Polyurethane (PU),Cellular ethyl acetate (EVA) or a combination of both of thethermoplastic elastomer Hytrel. A form of Hydrel of suitability is typeHTX8177 available from E.l. Dupont de Nemours, Wilmington, Del.

In FIG. 7 the alternate embodiment of a soledisk 32 and sole diskattachment structure 33 of FIGS. 3, land 10 provides excellentcushioning and traction at a footing surface, even with the shoe in acanted five degree configuration, within and by means of the saidstructure's rigid sole disk working with the flexible resilient wail ofthe sole disk attachment structure, as at 36, enclosing a sealed airchamber 4? which provides cushioning by compression of said air trappedin the chamber 4? in combination with the resilient flexing of said wall36 when a force is applied to said sole disk and which said wall 36structure's memory resumes its former shape when said force is relieved.But in an alternate embodiment if said air chamber is not to be sealedand the air allowed to escape when a force is applied by having anopening in wall 36 then the wall 36 can be made of less resilientlyflexible material and/or the said wall 36 can simply be made somewhatthicker to yield less easily to said applied force and/or the said airchamber 47 can be filled with a suitable foam material for beingencapsulated within said chamber 47 such as PU, EVA or SURLYN injectedinto said chamber by any known method or any other suitable material maybe employed to fill said chamber which chamber may be formed by blowmolding, or injection molding as with other parts all being within thescope of this invention. And the specific gravity of said chamber wall36 should be suitable to the specific gravity of a filler for saidchamber which filler generally should have a said specific gravity lessthan that of the chamber wall 36. All of these said features, includingallowing the shoe to freely turn even while either the outsoles heel orforefoot is frictionally adhered to a footing surface will reducetwisting stress of the shoe wearer's various foot and leg joint tendonsand ligaments and being particularly beneficial in this manner forpersons engaged in high stress physical sports, and also for the infirm,elderly or for those persons having foot and/or leg diseases orinjuries, or the shoe soles of this invention can be worn and used byanyone who simply wants to reduce lower body stress and maintain goodhealth thereof.

More specifically a shoe that can rotate independently at a fixed linearfooting position of its outsoles is best supported most beneficiallywhen said outsoles is made in the form of a disk coaxially connected topotentionally rotate in positional arrangement at the forefoot region ofthe shoe which encompasses the ball of the foot within the diameter ofthe said sole disk. The said sole disk preferably extending rearwardfrom the region of the toes first joint, as at 22, to include a regionof the ball of the foot, sat 23, FIG. 2. Then to attach the sole disk 16to the sole disk attachment structure 17 the sole disk's upper innerperimeter structure is beveled inwardly forming a circular flexiblyresilient lip, as at 24, having a horizontally projected undersurface 23which together form a clasp 26 structure and by which said claspstructure the said sole disk is resiliently snap-fitted to the shoe'ssole disk attachment structure 17 by first positioning the sole diskinner beveled perimeter of the clasp structure, FIG. 8 (see also FIGS.II and 12 for the position and sizes of said sole disk to shoe bottomoutsole and˜top view of sole disk including well 15 and upper steppedsurface 29 and clasp 26A) to engage the shoe bottom's sole diskattachment structure 17 complemental middle beveled perimeter structureFIG. 8. which together create a mechanically advantaged joining of saidcomplemental beveled surf Ices of the clasp and catch, as at 24 and 25when a force is applied forcing said beveled surface 24 to slide alongsaid complementarity beveled surface 25 therefore forcing the beveledsurface 24 to flex outwardly along beveled surface 25 until said soledisk clasp 26 is finally resiliently snap fined inwardly engaging intocircular catch groove 27 and onto circular catch groove shelf 28, FIG.3. And thereby clasp 26 is assembled onto said catch groove shelf 28completing the assembling of sole disk 16 to sole disk attachmentstructure 17, FIG. 9 in which said assembly said groove 21 and on whichsaid groove shelf 28 surface said sole disk attachment structure 17,held by and guided by catch 25 can rotate 360 degrees clockwise orcounter clockwise on sole disk 16 holding a shoe at a linear radiallyfixed position to a footing surface The sole disk attachment structure'sposition of rotation is reinforced, guided and stabilized by its bottomlevel circular downward projecting beveled structural region, as at 31,FIG. 8 that coaxially fits into complementarity formed sole diskcircular well region 15 reinforcing the sole disk fixed linear positionat said shoe bottom. The inclined surface ISA, FIG. 8 eases assembly.

The perimeter of the sole disk is sharply tapered to a point allow acertain degree of sole disk edge resilient flexing, such as illustratedin FIG. 6 to maintain a substantial contact of the sole disk to afooting surface when said sole disk moves with a shoe to a cantedposition from said footing surface, which cant occurs to just about thesame usual 5 degrees of cant before the foot of the shoe wearer isforced to be lifted, in response to upper body movement, entirely from afooting surface usually in response to a person making an abrupt sharpbody turn and/or when turning with the feet spread substantially apartwhich often occurs when playing sports such as basketball and tennis.The said feature of sole disk perimeter flexing as designed toaccommodate a shoe's canted configuration to maintain substantialfooting surface contact as are the inward beveled sides 108 ofintermediate outsoles 44 to substantially prevent canted shoe positionslips and falls and especially so on court surfaces made avoidablyslippery by being constantly spot wetted by drops of sweat from players.

The said sole disk perimeter flexing at a canted position also assuresthat the sole disk will never have an undesirable linear wheeling motionon the sole disks edge prevented by maintaining contact with a footingsurface substantially inward from the edge perimeter of the sole disk atwhich canted configuration said edge perimeter also comes into contactwith an edge region of the shoe bottom's sole disk attachment structure17, as at 48 which acts as a soledisk brake and locking mechanism asillustrated in FIG. 6.

The following alternate embodiment of a sole disk 32 and sole diskattachment structure 33, FIGS. 3, 7 and 10 for attaching a said soledisk 32 to the bottom outsoles of a shoe provides more cushioning forthe foot of the shoe wearer which is especially important for the heelregion of the foot that lacks the great shock absorbing flexibility ofthe forefoot's many springy joint ligament connections that veryefficiently absorb the shocks that occur with the aggressive physicalactivity of sports; unlike the heel that has only a little fleshypadding to absorb footing impact shocks.

Also in this alternate embodiment a shoe is made more unlikely to causeslippage on a footing surface especially when a shoe is lifted to theusual S degrees of a canted configuration to a footing surface, becausein said canted position, in this embodiment, the entire undersurface ofthe disk sole 32 remains in contact to said footing surface asillustrated in FIG. 7.

Along with the above mentioned features the said alternate embodimentalso has the same basic rotational means of a shoe's sole diskattachment structure 33 to rotate clockwise or counter clockwise to anypoint of 360 degrees connected to the circular top structure of a soledisk 33 upon which said sole disk attachment structure 33 can rotatewhen its attached sole disk 32 is frictionally held in place on afooting surface.

All drawing figure lines of said alternate embodiment define circular orannular structures. In the drawing of the sole disk attachment perimeterstructure 33 the rounded end, as at 35A, of catch finger 4, defines theperimeter of a circular opening of said structure 33 into which saidopening perimeter sole disk 32 is fitted and attached to. And said soledisk attachment structure 33 housing wall 36 and ceiling 38 all definecircular structures. The additional structural features of the saidalternate embodiment, as mentioned, allows the entire expanse of thebottom underside surface 34 of sole disk 32 to remain in fall contact toa footing surface by the sole disk attachment structure 33 dynamicallyreconfiguring its positional arrangement to a static position of soledisk 32 when shoe 19 and its bottom attached said structure 33 arecanting up to the usual said S degrees of hill cant that occursautomatically, such as when a foot of the shoe wearer has canted saidshoe in accompaniment to certain rapid twisting or turning movements ofthe upper body when that person is engaged in high stress physicalsports and the said shoe's said sole disk 32 and sole disk attachmentstructure 33 configures in a manner as illustrated in FIG.? where thecatch finger 35 of said sole disk attachment structure 33 is forced toflex upward at catch finger's rounded end 3M engaged at beveled catchgroove 41 of sole disk 32, and the catch horning shell wall, as at 36,of catch finger 35. is forced to flex somewhat outward as said shellwall 36 moves downward and eventually folds against the surface of thebeveled lower perimeter, as at 14, of sole disk 32, illustrated inFIG.?, as shell ceiling 38 comes down to rest against top end corner 37of sole disk at preferred angle of S degrees as shown in FIG. 7.

The sole disk 32 is attached to shoe bottom sole disk attachmentstructure 33 by placing the disk at its upper most beveled surface 40that provides a mechanical advantage when said sole disk is forcedthereat to slide upwards engaged to lubricated rounded end 3M offlexibly resilient catch finger 35 which defines the resting opencircular diameter of circular catch finger 35 opening which isresiliently stretched outward to open more widely as sole disk's beveledsurface 40 moves upward and forces said catch finger 35 to engageforcing nibs 42 (nibs 42 may be formed as a molded integral fixed partof ceiling 38, or said nibs may be placed as the heads of screws screwedinto ceiling 38, and said screws may be of a length sufficiently longenough to be used to attach the sole disk attachment structure 33 to thebottom surface of a shoe's midsole by screwing either a regular screwthread or self taping screw tread through said shell ceiling 38 into thebottom surface of said shoe's midsole) until said catch finger is forcedby said nibs 42 to resiliently map-fit inwards into sole disk's beveledcatch groove 41 creating—air-tight seal thereat for hollow space 50where said sole disk 32 is then held to shoe bottom sole disk attachmentstructure 33 that, can by these means therefor rotate clockwise orcounter clockwise to any desired radial segment position on sole disk 32at said sole disk's beveled groove 41 engagement to rounded housing wallcatch finger end 3M surface and where by wall 36 and sealed in air space50 of the housing of said sole disk attachment structure 33 saidstructure can substantially flex resiliently downward and upward andsubstantially cant to various directional positions relative to thestatic position of its ached sole disk 32 by which features the unitsubstantially absorbs the shock energy of impacts away from the shoewearer's foot and also substantially prevents disk sole 32 footingslippage.

The sole disk attachment structure 33 may be manufactured as anintegrated special fixed region of the shots midsole layer, oroptionally the outsoles layer with said structure and said midsole, orsaid outsoles formed as a single part by various molding techniques; orstructure 33 may be formed as a separate part and mounted and attachedto the underside of a shoe by any known method or practical meansincluding attaching by screws for instance would allow the saidstructure 33 to be readily removed from the shoe as a complete unit withattached sole disk 32. Manufacturing of said unit can only beaccomplished by any outside party only by written and signed consent ofthe inventor.

The said sole disk attachment structure of either embodiment may be madeof any internally lubricated material, and a lubricant of stableviscosity may additionally be placed onto a beveled clasp or catch oronto the end of catch finger 35 and/or beveled surface 44 to assure easeof assembling of a unit or for creating an air tight seal for the hollowair space 50 of sole disk attachment structure 33.

The said sole disk of either embodiment can be readily removed fromtheir corresponding sole disk attachment structures by placing the flatend of a tool such as for example a conventional screwdriver into airspace between the perimeters of a soledisk and its soledisk attachmentstructure as for example 109, FIG. 9 and prying said soledisk from itsattachment structure.

The sole disk 32 and sole disk attachment structure 33 of the alternateembodiment of FIGS. 3. 7 and 10 can be employed for uses either the heeland/or forefoot region of a shoe and will be useful when used with anystyle or type of shoe, and will work especially well with shoes of verylarge length and width sizes with which the said sole disk 32 diametersize necessary for the shoes width may extend rearward somewhat—thebendable forefoot region of the insole at the ball of the foot of a shoewearer, and the said sole disk 32 will work properly thereat when theshoe is bent to the extreme due to the greater resilient flexibilitycapability of the said alternate embodiments structural means of an airspace, nat 50, of the sole disk attachment structure 33 to the disk soleof a shoe to conform to extreme bending of the sole layers of said shoe.

Either embodiment of the sole disk and sole disk attachment structurecan be bulk to any practical size and to any sout of foot or leg gearintended for human or aninial use such as nmy be exemplifled in FIG. I6structure 46 having through holes 45 for screws for attachment of aproper size to the hoofs of horses or adhesives may be employed torholes 45 in another embodiment may be provided in a thinner and smallerthickness of structure 46 for use with pop-rivets to attach thestructure to a belt or any sort of leg gear, or then again, adhesivesemployed for adhering a unit of the invention to any kind or type ofcloth, plastic or leather fabricated to fit the feet of humans or thehoofs and paws of animals.

FIGS. 13-17 show alternate embodiments of sole disks 51 and 51A and soledisk installation structures 52 and 52A that may be a preferable choicethat is more practical to function with many types of dress shoes andboots and other type shoes that normally have midsoles and outsolelayers fabricated from pre-existent flat sheet stock of leather and/orman-made materials, in that resect the old standard dress shoes or bootsand sonic others that are new, or sold and in use or second hand canhave their pre-existent manufactured shoes convened to install thisembodiment of the invention by having said shoe's midsoles and/oroutsoles replaced with the sole disks and sole disk installationstructures of this invention made from said leather and/or man-made flatsheet stock as illustrated in FIGS. 13-17. And also shoes having the oldsaid style or new style new standard uppers may be manufactured for salewith this said inventions units already installed with inventor'spermission.

The said structures of this alternate embodiment of the invention mayalso be made by special order man-made materials in whole or in put asdisclosed earlier in this specification.

All of the above acquirements for the fabrication and/or installation ofthis invention either assembled or not assembled or any part thereof canonly be fabricated, acquired or installed only by written and signedcontractual consent by the inventor.

The fabrication of this said embodiment of the intention can beaccomplished with signed permission of the inventor by the ordinarytools of the everyday shoe repair shop for sale or installation on newor old shoes and shoes custom made for customers.

Parts for the simple construction of this said embodiment can bemanufactured or fabricated in the manner that follows which as disclosedapplies to both the heel and forefoot units of the invention beingdisclosed at times by reference numbers of the forefoot unit which maybe assumed to also refer to the heel unit as they the reference numeralsobviously may be applied without nun] application in a drawing figure.Said embodiment parts can be cut or die stamped from flat sheet stockmaterials and farther fabricated by stitching and/or the application ofadhesives and also by employing screws to saw parts together and alsofor installation of units of the invention onto the soles of shoesincluding the application of heat to adhere parts together. Parts areeasily matched for assembly accordingly to each parts profile an cutfrom flat sheet stock accordingly to the drawing figures of thisspecification including part profiles or silhouette shown by way ofbroken lines making up the whole of a region oft put

The multi-co-axial circular lines that define the structure of soledisks 51 and 5IA make up the whole of the said sole disks which a largevolume manufacturer thereof may prefer to be formed by being molded intoproper form by the injection molding process or other known moldingmethods.

The said sole disks also can be made as a two part or three partfabrication. With a two part application the bottom layer, as at 51,outsole region which contacts a footing surface may be a separate rubberpert made from a rubber material that has an excellent traction propertythat is bonded or sewn to the other disk part, as at 51C and 51D, FIG.14. A three pert disk fabrication may better be suited to small volumeproduction of the said pert such as by a shoe repair shop that couldsimply die-stamp all three parts of different diameters from twothicknesses of flat sheet stock. The two outer parts' as at 51C and 51,FIG. 14, having the same thickness but different diameters asillustrated in the cut-away drawing of FIG. 14. And the intermediatepart as at 51D, would then have the greatest thickness and smallestdiameter than the other two puts to which said parts 51C and 51 it isassembled between. To fabricate said three parts of a sole diskintegrally together as a single pail. Adhering the parts together bytoday's excellent strong bonding adhesives may be the most practicalchoice by applying an adhesive to all touching surfaces and thenstacking said parts coaxially together in a properly precise made jigfor the purpose with the largest diameter disk part on the bottom andsmallest size diameter disk stacked next and then the last pert stackedon top of the other two and then a ¾″ flat plywood disk the diameter ofpant 51C finally coaxially placed on top of said parts then clamping allsaid parts tightly together until their adhesive has set thus making abonded single integrated flat sole disk 5 part having a preciselygrooved coaxially concentric integrated perimeters.

The two top adhered said disks of said sole disk 51 part may be made of(or all three, if another outsole bottom layer is added for the largestdisk size to serve as a glued on but removable said sole disk 51 partthat provides said sole disk 51 part with a bottom footing surface ofincreased traction) Lubricomp's Internally lubricated compounds of lowerwear and lower friction such as graphite filled and silicone filledACETYL or the LNP material, a PTFE and arimid filled Lunbricomp ACETYLthat give more than five times better resistance to abrasive wear thanunfilled ACETYL; also Lubricomp's polyurethane containing a proprietaryfiller of theirs could provide the needed self-lubricity. And asaforesaid, these chemicals modify the surface of the part to provide an“INTERNALLY LUBRICATED’ compound, but the presence of the lubricant doesnot affect the physical properties of the rubber part Any of the said“internally lubricated” materials, which lubricant is bound to the partmaterial may be optional choices disclosed in the specification andothers that provide maintenance-free lubricated parts withoutsignificant transference of the internally bound said lubricants toparts being lubricated; which parts lubrication features are highlydesirable and will be optional choices to be employed in all embodimentsof this invention as well as other like substances.

The assembled layered parts of the forefoot unit of this embodimentshown in the cut-away view of FIG. 14 along lines and in the directionof arrows 13-13 FIG. 17 are shown and named in reference to the shoe'sforefoot installation of the this embodiment of FIG. 17 shown in sideelevation and of which named parts also relatively correspond to likedparts of the heel unit installation of the embodiment of FIG. IS and asshown in the cut-away view of FIG. 16 along the lines and in thedirection of arrows 16-16 of FIG. IS. all of which are fully disclosedwithin the following specification.

The shoe's midsole, as at 52B of the cut-away view of FIG. 14 and bottomshoe sole view of FIG. 13 forms the first layer of said sole diskattachment structure 52 and as relative to FIG. 16, cat S2C. The secondlayer is formed by shim 52D which fits between the midsole 52B andoutsole 53 FIGS. 13 and 14, and fills all of the space there betweencontiguous to broken line top perimeter of sole disk 51. Likewise theshim 52E of FIGS. 15 and 16 serves the same purpose as said shim 52Dillustrated in FIGS. 13 and 14 (which is to support separated positionsof outsole 52A and midsole 52C and allows soledisk 51A to rotate freelyat groove as at 51D FIG. 14). Said shim 52E, FIGS. 15 and 16 is cut tothe same silhouette as outsole 53A and—inner annular cut of said shim52E is cut to contiguously follow the broken line outer perimeterstructure of sole disk 51A. Said shims 52D and 52E supports andstabilizes outsoles 53 and 53A positions as mentioned, as at and on thestepped 51C and grooved 51D periphery of said soledisks 51 and 51A atwhich said step 51C and in said groove 51D said outsoles,as at 53 FIG.13,and as at 53A FIG. 16 hold said disks 51 and 51A in position atmidsoles 53 and 53A attachment to upper shoe (shoe not shown) whichtherefor guide and hold the upper shoes to rotate on and around saidsole disks by shoe wearer clockwise or counter clockwise as indicated byarrows. Said outsoles 53 and 53A can be attached and held in place tosaid midsole by self-tapping screws, as at 54 and/or by applyingadhesives which also hold said shims in place. Said attachment means canbe employed to attach outsole 53 to Midsole 528 of FIG. 13 except saidadhesive would not be applied no farther rearward then the secondrearward half circle region of sole disk SI FIGS. 13 and 17, with theremaining rearward removable flaps 538 portions of said outsole 53 heldin place by only six self-tapping screws, which said screws can beremoved and lime two said outsole flaps 538 lifted away from said soledisk in order that said sole disk can be removed and repaired orreplaced with a new sole disk, which new sole disk may have any kind oftread design including changes in design of the sole disk itself to meetany kind of change of use or application of said shoes being re-soledwith the new sole disks. This embodiment of the invention has all of thesame basic functions as functions of all prior embodiments of theinvention (except that it has no significant shock absorbing function)including a resiliently flexible disk sole perimeter which can flex toapproximately 5 degrees to accommodate a canted position of shoes of theshoe wearer which said shoe's disk soles flexed perimeters maintainsgreater edge region tractional contact on a footing surface to moreefficiently prevent slips and falls by the shoe wearer than canconventionally soled shoes of this type.

In the shoe heel region embodiment of attached sole disk 51A and soledisk attachment structure 52k FIG. 15 and 17, the sole disk 51A also hasa resiliently flexible perimeter as at 51G, FIG. 15, that has the samefunction as disclosed for sole disk 51 flexible perimeter 51B, FIG. 17.Also in this embodiment the shim 52E and outsole 53A are held inposition preferably only by self-tapping screws, as at 54 which alsohold sole disk 51A in position and which said sole disk can also beremoved and replaced by removing and then reinstalling said self-tappingscrews that first allow said shim and outsole 52E and midsole 53A to belifted away from said sole disks for sole disk removal and replacementand self-tapping screws reinstalled to tie the unit back together again.The heel region embodiment of the invention also has all of the samebasic functions sail—embodiments of the invention including sole disksole perimeter resilient flexing but not a significant shock absorbingfaction.

A shoe having a unit of the said invention installed on its sole heelregion and forefoot region cannot rotate on sole disks at both saidregions at the same time but can only rotate on a single sole disklocated either at the said heel region or forefoot region and only whenthe shoe wearer lifts either the shoe's forefoot region sole disk off ofa footing surface to rotate on said heel region sole disk; or lifts theshoe's heel region sole disk off of a footing surface leaving only saidshoe's forefoot region sole disk to rotate on. And when said heel soledisk and said forefoot sole disk are both on a footing surface at thesame time of the same shoe neither sole disk will be able to rotate andsaid shoe will have full non-slip fictional in place traction.

As aforementioned, assembling of the unit parts of this embodiment ontoa midsole of a shoe is to simply match the profile silhouette of eachpart as by first preferably placing sole disk 51 FIGS. 13 and 14 on ashoe's midsole 52B (having first removed the old standard outsole fromold shoes or prior manufactured new shoes; or optionally installingdirectly onto an outsole therefore double soling a shoe with said unit)and then adjusting placement of said sole disk with placement of theforward toe piece of shim, as at 521). And after clamping said shim 52Dand sole disk 51 properly in place on midsole 52B then placing theshim's two separated end flaps, as at 52F, in place snugged up againstthe sole disk and toe shim and clamping all said parts in place and inlike manner install the outsole's four pieces, as at 53 and 53G, andfinally installing all outsole self-tapping screws, as at 53A. and theninspecting units perimeter to see if any excess material needs to betrimmed off to complete units installation on shoe's indsole. It isnoted that some of the shim and outsole part's materials may be flexibleenough to work into outsole's groove 51D FIG. 14 cut as single pieces ofshim and outsole materials instead of two or three cut pieces thereof.

The rearward portion, as at 51E, of sole disk 51 is left free of shim52D and outsole 52 parts to allow very large diameter sole disksnecessary for very large shoe soles to remain flat in traction against afooting surface when the shoe wearer lifts a shoe's heel region off ofsaid footing surface and therefore must bend the forefoot region of theshoe at the ball of the foot of the shoe wearer as exemplified in otherembodiment illustrated in FIG. 2 where the shoe size requires theextra-large forefoot region sole disk sole, where however the other saidshoe embodiment is small enough to fit the shoe's forefoot sole disk 16at or forward of the apex of the bent outsole 4-4 at the ball of thefoot of the shoe wearer and therefore the said sole disk 16 remains flaton a footing surface as illustrated.

In the embodiment of FIGS. I and 2 the sole disk 16 as illustrated inFIG. 2 can be modified to also free up a small rearward portion of thesole to fit and work well on shoes of very large length and width sizessimply as shown in the exploded view of sole disk's sole diskinstallation structure of FIG. 4, and assembled view of FIG. 5 bycreating a rear inclined area of catch groove shelf, as at 258 whichopens said sole disk groove 27, at inclined groove shelf 288 and alsoinclining the widened region of sole disk groove wall 27, as at 28Cinward, thereby freeing-up sole disk installation structure at rearwardregion to freely bend up and away from a rear end region of the soledisk 16.

The horseshoe embodiment below of this invention shown in FIGS. 19-22 isdesigned to decrease or stop twisting forces that presently do occur toa horse's legs and often cause serious injury when shod withconventional horseshoes that have protruding horseshoe nail heads andvarious horseshoe tread ridges designed for traction that can easilysnag on various pathway surface materials, especially hard and semi-bardman-made materials the horse may be on.

FIG. 19 shows the full curved profile of a horseshoe of this inventionwhich perimeter does not define the arc of a perfectly circularstructure. But all seventeen rollers 73 are in positional arrangementsin the bottom curved structure of said horseshoe with all of theirhorizontal axes of potential rotation pointing to a common central pointof a hoof determined to be the vertical axis of potential rotation of ahorses hoof about which the rolling surfaces of all rollers will, whenrequired, roll about following their individual circular orbits ofrotation around said vertical axis of said hoof which therefor avoidssnagging an small obstacles on the pathway of a horse; which said rollerfeatures are exemplified in more detail as follows:

When a horse, shod with horseshoes of this invention, is stepping alonga pathway and brings a hoof down onto said pathway where, by chance,small obstacles on the pathway are then touching various sides of theprojecting flat ends 95 of a horseshoe's rollers 73 and the horse thenbegins changing direction with a rotational movement of one or more ofits hoofs kept linearly in place on said pathway. Question: Will thehorse's said in place turning horseshoe of one or more hoofs becomesnagged at said pathway obstacles which are touching the straight sidesof the said horseshoe's rollers 73 when die horse attempts to rotate itssaid horseshoed hoof or hoofs either clockwise or counter clockwisearound the vertical axis of a hoof The answer is no the said hoof willnot get its horseshoe snagged on said pathway small obstacles becauseeven when two such obstacles are touching both flat ends of any or allsaid roller 73 such as, for example, the fifth roller at the right sideof the bonds horseshoe moving clockwise of which the said obstaclestouching the sides of said fifth roller 73 must therefore lay at dieoutside of the circular orbital movement of said roller which saidroller will take and therefor will neither move against nor most awayfran said pathway obstacles touching the said straight sides of rollerbut merely brush against said roller without increasing contact pressureas said roller follows its said orbital movement of the horseshoed hoofsrotational movement about its vertical axis at said pathway unimpeded bysaid obstacles. All but two rollers 73 at the ends of the horseshoefollowing the fifth roller mentioned will roll over said obstaclerolling within and outer region of the said fifth roller's orbit withthe fifth next to Inst said following roller 73 at the opposite leftside fork of the horseshoe also only brushing against said pathwayobstacle and not increase pressure against it, and the followingremaining four rollers of said opposite fork of said horseshoe will eachfollow orbits that are at the inside region of first said fifth roller'sorbit and therefor will also roll over the obstacle that was at theopposite inner flat side of said first fifth roller but will not rollover obstacle at opposite end of said roller. In other words allseventeen rollers of the said horseshoe will either roll along thetouched side of, roll over or entirely miss any random positionalarrangements of pathway small obstacles without any said pathway smallobstacle becoming snagged at said horseshoe rollers. Other featuredfactions of said rollers and accommodating structures of the horseshoeto deal with and avoid adversarial hone pathway objects are disclosedbelow.

It is well known that serious injuries often occur to the legs of homes,and mostly to their complex lower legs regions including inflamationand/or tearing and separation of their Sesamoidean ligaments, Suspensoryligament of the navicular bone, T-ligament, Common extensor tendon,Annular ligament Deep flexor tendon, Impar ligament Coffin joint.Pastern joint and Fetlock joint which injuries are often brought on byover-extension resistance to abnormal physical twisting forcesoriginating at the hones hoofs not moving as they should in coordinationwith the horse's upper body movements as the horse places its weight ona conventionally shod hoof which had become perhaps only momentarilysomewhat snagged on a pathway surface obstacle while attempting to turnits body but nevertheless often eventually causes end disease seriousinjury and great immobilizing pain to a horse. Concrete with a roughsurface to prevent slippage is often found as the floor material ofchoice for horse stables and which is a primary example on which surfacehorseshoes of a hone may time and time again become momentarily snaggedat and generally somewhat resist twisting sliding movements of a horseshoofs, which action most of the tine goes unnoticed by a horses handler,unless the home is seen to have been actually tripped by said obstacle˜and gradually causes serious inflamation first, and over time, asconcerns the horse's suspensory ligament, may degenerate to incurableend disease states such as the one known by vets, as DegenerativeSuspensory Ligament Desmitis (DSLD), and then if the hoof finallybecomes sagged hard enough, and again for perhaps only for a splitsecond, may cause a ligament or even a tendon to eventually becomepermanently stretched or even partially or filly torn loose from a bonejoint or muscle and the degenerative cause of the injury remaining amystery. The common paving material called asphalt may also be a riskysurface for a horse to walk on, especially black asphalt which absorbsheat from the sun easily and somewhat softens, and anything projectingfrom a horseshoe can get easily get caught up hard into its surface. Andother surfaces are also risky, such as the expansion grooves ofsidewalks and wooden boardwalks. In other words most man-made surfaces,hard or even somewhat soft, are not kind to a hone's legs. Such surfacesrepeatedly cause stress to horses so insidiously that homes come to saidincurable disease Mates with handlers never noticing before hand thatthese hones are being stressed in ways just disclosed. It should,therefor, be realized by horse owners that a horse might be constantlyin pain from sore hoofs and legs caused by such pathway materials butnot injured enough to have a noticeable limp or other signs of injury.Think of people feet which some hurt badly but people often don't showit in the way they walk. And it should be realized, too, that the lowerlegs of horses that are designed by nature town hard on all kinds ofnatural surfaces are not particularly very sensitive to pain andtherefor when a horses legs are stressed the horse most of the time doesnot react emotionally to the stress, not even to chronic leg diseasesbefore the end stage of the disease.

The said horseshoe embodiments of this specification are designed tohave a long serviceable life with features to decrease or prevent saidtwisting forces from occurring to a horses legs in such a manner as tobe most comfortable and safe in their application with minimumtransference of heat, vibration and shock from said horseshoes to thehoof of a hone while allowing free flexing of not only the frog regionof the hoof but free flexing of the entire wall of the hoof whileproviding overall reduced stress to a horse from outside fortes. Saidhorseshoe has eleven parts for its installation to a hoof Said horseshoeparts as shown in FIG. 22 are as follows:

Main one piece horseshoe body 86 which has the silhouette profile of thehorseshoe. Resiliently flexible spring 75. Roller box 74. Roller 73.Resiliently flexible bottom layer 77 and integral roller keeper sealflaps 77A (an additional foam layer may be added to provide insulation).Thin flat steel or high impact plastic bottom cover plate 94, which hasopen regions for roller keeper seal flaps 77A and cover plate screws 14.Said cover plate 94 protects and holds flexible bottom layer 77 andintegral roller keeper seal flaps 77A in place against the main body S6of the horseshoe. Small self tapping screws 14 screw through bottomplate 94 and through flexible layer 77 and into horseshoe main body 86to scan said bottom cover plate 94 and said flexible layer 77 to bottomof horseshoe. Large interior self-tapping horseshoe screws 91 secure themain body S6 of the horseshoe to the hoof of a horse in a special uniqueway to allow the frog region and entire wall of the hoof to flexnormally slightly outward and resiliently back inward (most horsehandlers and owners still think that only the frog region of the saidhoof has flexural movement) which said normal hoof flexing action actsas a shock absorber which helps to reduce concussion on the hoof andlegs of a horse when contacting a pathway surface.

It is important to know why it is so important to allow flexing of theentire hoof wall explained as follows: As mentioned, the horse hoovesare extremely complex structures, very sensitive to stress and pressureand with an excellent blood and nerve supply. On the outside andunderneath, they are protected by a horn, generally known as the wall ofthe hoof (a form of modified, hardened skin) which grows down from thecoronet band, a fleshy ridge around the top of the hoof equivalent tothe cuticle on a human nail. Inside the hoof the horny (wall) outerstructures are tightly bonded to the sensitive ones by means of leavesof horn and flesh (called laminae) which interlock around the wall ofthe hoof The sensitive structures themselves surround the bones of thefoot. When weight is put on the foot (hoof) it flattens and expandsslightly, (flexes outward) squashing the sensitive tissues and bloodvessels between the horn (wall) outside and the bones inside. The bloodis squeezed up the leg into the veins, which have valves stopping theblood naming back again. When the weight is removed (from the hoof),fresh blood rushes back into the tiny vessels (called capillaries) andso the process goes on.

It was thought until very recently that it was almost entirely pressureon the hoofs frog region which pumped the blood around like this, butrecent research has shown that, although the frog plays a part; it isthe expansion of the whole foot (allowed by flexible expansion of thehoof wall ) which is important The frog region, together with the plantscushion inside the heels of the hoofs foot, mainly helps reduceconcussion on the foot.

Today millions of horses feet are tied to horseshoes which do not allowproper blood flow to their legs which may be another contributing factorof leg tissue breakdown which can lead to the widespread disease knownas DSLD above,

When shoeing a horse with a horseshoe unit of this invention whichallows fill free outward flexing of the entire wall of the hoof the saidhorseshoe unit may be precisely positioned on the hoof of a horse byknown & as a professional farrier knows, the anatomy of the bottom partsor regions of said hoof. The forefeet hoofs have a different anatomyconfiguration orientation than that of the horse's hindfeet hoofs. Thesaid forefeet hoofs are much more round in shape than the hindfeethoofs, the hindfeet hoofs being much more pointed in shape than are theforefeet hoofs. Therefor said horseshoes will be made in shapes forfitting to either the said forefeet hoofs or said hindfeet hoofs as wellas coming in different sizes in accordance to the size and type of horseto be shod. All sizes and shapes of said horseshoes have rollers, whichas disclosed, will self-adjust automatically to the vertical axis ofrotation of all types, sizes and shapes of a horse's hoofs. And all saidhorseshoes will have a horseshoe main body 86 horseshoe screw holesformed large enough to accept various degrees of outward movements ofscrew shanks 96 within screw hole air space 97 to allow a safe andproper full magnitude of flexing of a hoof wall for all types of horsehoofs below. Prior to Adding any type of horseshoe to a horses hoof thesaid hoof must first be properly filly prepared for accepting ahorseshoe in accordance to the particular condition of each individualhoof In addition horseshoes of this invention require that the bottomsurface of a hoof and especially as concerns the hoof wall should bemade as homogeneously flatly level and smooth as possible in order forthe said horseshoe, which will allow said hone's hoof wall to flex onits surface, to have a complete closely fitted contact with said hoof.Also a stable viscosity water seal grease, nil grease or any suchproduct compatible to the health of the hoof should be applied betweenthe bottom surface of said hoof wall and top surface of said horseshoeto assure freedom of flexibility of the hoof wall on said horseshoe.

The horseshoe is attached to the said hoof by the special and uniqueinteractive structures of the horseshoe screws 91 and horseshoe mainbody 86 horseshoe screw hole 89 structures which together accomplishcomplete flexural freedom of a hoofs flexible wall. The large diameterself-tapping threaded 99 region of screws 91 have smooth round shanks 96of much nailer diameter than said screw threat 99, and which said shank96 diameter is directly attached to the screw head 90. The horseshoemain body 86 screw hole 89 is minutely smaller than said screw threaddiameter region 99 which permits a snug or partially screwed in fit ofsaid screw's thread region 99 to said main body screw hole 89 wall. Saidlarge self-tapping horseshoe screws 91 attaches the horseshoe main body86 with roller boxes 74 and rollers 73 already assembled in it to ahorses hoof wall in the following manner: First, with the horseshoe mainbody 86 downside turned up, self-lubricating washers are placed ontoscrew hole's bottom end right angled screw head housing overhead surface102, as at 100 and lot, Fi& 22, which act as self-lubricating screw headflat washer bearings which may be made of internal-lubricated materialssuch as Acetron NS or Parker Compound N1090-85 or PTFE Compounds orHytrel Type HTX-8177 which may also be primary or optional choices ofmaterials for other parts of the horseshoe, The first larger washer 101has a round axial hole of a diameter slightly larger than the diameterof screw hole 89 wall diameter, and said washer 101 has—outer perimeterdiameter which completely coven right angled screw head housing overheadsurface 102 to diameter of said housing's vertical wall 104. Next aself-tapping horseshoe screw 91 is screwed or force fitted into screwhole 89 which precisely guides said screw 91 to a position therein asillustrated at the left side of drawing Pig. 22 with a small portion ofscrew point projecting from top of horseshoe main homing 86 surfacescrew hole 89. To properly gauge the depth of all said screw shanks 96into said screw holes 89 and magnitude of projection of said screws 91pointed ends projecting from said horseshoe main body 86 a simple screwgauge of proper length can be made from round molding of a diameterlarger than that of screw head round housing wall 304 diameter and cutto proper length and grooved along its long axis to accept screw shanksand placed sequentially onto all said screw shanks 96 with one end ofsaid gauge placed against underside of screw head 90 which preciselylimits the length of all said screw shanks 96 to the same depth lengthscrewed into said screw holes 89 and therefor also the—magnitude ofprojection of each screw 9 point projecting from said horseshoe mainbody 86 screw holes 39 as illustrated at said left side of drawing Pig.22 All remaining horseshoe screws 91 and washer 101 are assembled in thesame manner and configuration into said horseshoe main body 86 screwholes 39. The second said nailer washer, as at 100, has a two part splitaxial hole diameter that is assembled to all horseshoe screws 91w snuglyfit onto screw shank 96 diameter, and said washer 100 has—cuter diameterof the same size as the screw head diameter. Next a proper length ofpreferably coiled fatigable resiliently flexible oblong hollow plastickeeper tubing 103 is forcefully slightly compressibly fitted completelyaround and between screw head 90 screw head washer bearing 100, andscrew head housing vertical wall 104, and against washer bearing 101.Tubing 103 as shown placed therein keeps screw shank 96 reboundablycentered within screw hole 89 air space 97; below. The said horseshoemain body 86 top is greased and is now ready to be carefully positionedby a farrier onto the uplifted prepared hoof of a horse and all saidassembled horseshoe screw heads 90 with points projecting from thehorseshoe main body 86 to the same length are all lightly tapped at thesame time by employing a small piece of ¾ inch plywood onto all saidscrew beads 90 and centrally striking said plywood moderately with ahand sledge until all said screws 91 projecting points have been driveninto the wall of said hoof and then said plywood removed and saidhorseshoe main body 86 is then pulled off of hoof and all the horseshoescrew indent marts left in said hoof wall by said horseshoe screws areinspected to be sure that they we all correctly positioned for safecomplete driving of screws all the way into the wall of the hoof andhaving passed inspection for correct positions the horseshoe main body86 is then repositioned back into hoofs said the prior screw indentsmade and all said horseshoe screws 91 driven all the way into the hoofwall ending with all of the screw's threaded region 99 screwed into thehoof wall leaving only the screw shank 96 centered in screw hole airspace 97 with the said screw heads lightly pressured against thehorseshoe main body 86 and finally all screw heads 90 are torqued to twofoot pounds of torque each, by employing preferably a battery operatedpower screw driver equipped with an adjustable torque gauge with anautomatic click release. All said screw heads 90 having been fillyseated on their washers are backed off slightly with one eight turnsuntil the farrier can feel some slight sideways movement of saidhorseshoe main body 86 on the hoof by said farrier pushing hard on theside of said horseshoe main body 86 and having accomplished that laststep the said horseshoe main body is now fully mounted to the undersideof the hoof. Then the flexible layer 77 is properly mapped onto theheads of all bottom plate screw 14 heads. Next the bottom plate 94 ismounted in place by slipping bottom plate 94 keyholes onto all extendedbottom plate screw 14 heads and pushing said plate to one side to lockit in place and tightening down all said screws 14 and the horseshoe'sfill assembly is now mounted to the hands hoof Mounting of the horseshoemain body 86 in this manner allows fill free flexing of the hoof wallbecause the full length of the horseshoe screw's large diameter threadedends 99 have all been screwed into the hoof wall leaving only the muchsmaller diameter screw shank 96 left in horseshoe main body 86 screwholes 89 with a large air space 97 left fully around said position ofscrew shanks 96 and therefore when a horse steps down on a pathway thewall of said hoof flexes outward with said treaded region of horseshoescrews 9! fixed in place in said hoof wall and therefor moves thesmaller diameter attached screw shaft 96 with it to one side of screwhole 89 air space 97 and therefore too, also slides the screw head 90with self-lubricating washer ICC to one side of screw head housing 104compressing keeper tubing 103 to the right and left sides of screw headhousing walls 104 at the right and left arced sides of horseshoe andtherefor the weight of the horse on its hoofs outward flexed walls keepsthe horseshoe unit always in a proper stable positional arrangement onany said hoof the horse may be standing on or walking and running onbecause each screw attached to the flexed wall of a hoof, while saidhoof remains standing on a surface, has moved outward at a differentradial segment angle plane at each installed site at said right and leftarcs of the horseshoe and also of the right and left arcs of the hoofwall However if said raised horseshoed hoof did not have automatic selfcentering means to the hoof of the horse and the horse brushes a shodhoof against anything on the way up the hoof's horseshoe could beslightly moved on the hoof and therefor no longer centered on it for thenext step downward, but this cannot happen because all resilientlyflexible keeper tubing 103 wrapped at each bead 90 of the horseshoescrew would be compressed by movement of said screw head 90 to anydirection off center of screw hole 89 and therefor all said resilientlycompressed tubing 103 would thereafter rebound against said screw heads90 which ganged action always moves said screw shanks 96 back to centerof said screw holes 89. The horseshoe main body 86 screw holes 89 willbe of one sufficient diameter size universally large enough to allowsafe free full flexing of any size or kind of hoof to any degree ormagnitude of hoof wall flexing made possible by employment of saidresiliently flexible screw head keeper tubing 103 aforesaid centeringmeans disclosed for centering screw shanks 96 within screw holes 89 airspaces of one common maximum size screw hole 89 for many different sizesof horseshoes.

The main body 86 of the horseshoe is preferable made ofUltrahigh-Molecular-Weight Polyethylene which resists abrasion, is tearresistant and has vibration dampening and heat absorption resistantproperties and is easily molded and/or machined. The rollers, as at 73may have flat rolling surfaces, as in FIG. 19, or preferably haveslightly concave rolling surfaces, as exemplified in drawing FIG. 21, asat 79, (shown exaggerated forsake of illustration) that provide minimalsurface contact to a hot surface of horse pathways while allowingcooling air flow to flow between said hot surface and the arched concavesurface of said rollers; and said roller concave surface also providessharp corners of minute radii for minimal roller bearing surface contactwith the bearing surfaces of roller box 74 in the main body of thehorseshoe, therefore, broad areas of bearing surface wear of rollers 73is avoided and heat transference of said rollers to a horse's hoofs isheld to a minimum while said rollers 73 small bearing surfaces spreadout wear against the much more broad bearing surfaces of the arcedcorners and overhead of roller boxes 74; which rollers 73 actions givesthe internal-self-lubricating property of roller boxes 74 bearingsurfaces long lives.

The horseshoe writ is attached to a hoof with self-tapping horseshoescrews and threaded holes thereby formed in the hoof wail of a horse canbe used over again a number of times when exchanging the basic identicalhorseshoe main body 86 FIG. 22 of a horseshoe of the invention that willbe made in a choice of sizes to fit a variety of horse hoof types. Agiven length of a horseshoe screw with self-tapping screw threads hasmuch more holding power than that of the same length of a tapered smoothsided horseshoe nail that must take a different—of entry and be highlyforce fitted into a hoof each time a new horseshoe is Installed leavingclose by healed and open scars in the wall of the hoof where earliernails have been driven ‘in with a hand sledge and removed and leave morestress damage to a hoof and cannot be placed and then driven into the ahoof wall—accurately as self-tapping horseshoe screws can be into therelatively small width of space occupied by the hoof wall by beingprecisely power screwed with said screw pulling itself into a hoof wallwhile shaving away a precisely consoled unstressed pathway threaded holeinto said wall with precision guidance provided by the horseshoe's mainbody 86 horseshoe screw guide holes 89 to which said horseshoe screwsfit snugly into and are guided to a predetermined precise sat angles ofdirection into the wall of a hoof causing no entry stress and withoutchance of straying into any sensitive region of the hoof as sometimesoccurs when a farrier sledges in horseshoe nails which have a longtapered structure of which a conventional horseshoe nail hole cannotaccurately guide as said farrier hand sledges these said horseshoe nailsguided only with the farriers two fingers only part of the way into ahoof with high force sledging tops˜aside and permanently highly compressparts of the hoof at the nail's entryway and exit hole where theprotruding nail end must then be sledged sideways onto the hoof foradded holding power and excess twisted off which is the old crude way ithas been done for hundreds of years and persist until the present dayand horses still suffer today by this predominate crude way of shoddinghorses with the usual iron horseshoes which work should be done assafely as it can be done only by the expert work of highly professionalfairies which today are very hard to find and a dying breed. Today mosthorses are shod by part time neophytes who call themselves “farriers

The horseshoe's rollers 73 all have a horizontal axis of rollingrotation which lay at a different radial axial plane from any other saidroller because the horseshoe structure does not define a perfect circlenor neither does the hoof wall of a horse, therefor each roller'shorizontal axis of rotation must be placed differently into thehorseshoe to have the potential to roll around the vertical single axisof a hoof with all said rollers said horizontal axis in their radialsegments pointing to said single vertical axis of potential rotation ofa horse's hoof necessary to allow each said roller to potentially rollalong its own individual coaxial annular path of least resistance aroundsaid hoofs vertical axis.

Each roller 73 has two flat constant tight angled vertical plane sidesas shown in FIG. 23. Therefor each said roller has flat end surfaces atright angles to the roller's horizontal axis of rotation. And becauseeach said roller follows a circular pathway each with a different radialline segment axis of rotation that joins to the single vertical axis ofsaid hoof, each said roller's sharply cornered vertical plane sidestherefor are each presented radially to a pathway at different radialsegments of lateral angles of attack to the surface of said pathway,either hard or soft, to resist linear force of movement of a horse'shoofs in 17 different directions presented by said 17 rollers of eachhoof's horseshoe on said path when a horse is either standing on anincline or in stepped tractional movement on an icy pathway with saidhorseshoe's concave rollers providing reliable traction, and at the sametime said potential rolling movements of said rollers 73 of the horse'shorseshoes allow easy turning movements when required of a hoof torotate about its said vertical axis while still providing excellentresistance to linear slippage in any direction of said hoof with thesaid horseshoe rollers magnitude of projection from a horseshoeempirically adjustable to provide only a practical safe force of generalresistance of horseshoe pathway slippage generally applied to allsurfaces m a manner not stressful to a horse accordingly to itsparticular footing environment and also relative to the horses size,weight and type of predominant physical activity to allow some safehealthy slippage to occur to avoid stressful abrupt stoppage ofmovements of the horse's legs. The amount of projection of said rollers73 from the horseshoe main body 86 is determined by the vertical lengthand wire thickness of the coil of springs 75 of which a variety ofspring 75 sizes will allow custom adjustments of the magnitude ofprojection of said rollers 73 to a limit of projection, as illustratedin FIG. 22. said spdngs 75 can push a roller box outwards from a rollerbox compartment which said compartment be formed somewhat verticallyhigher than shown to allow a greater variety of said projection andstill have room for substantial compression of spring 75 to properlywork the shock and ventilator features afore disclosed of the horseshoe.

In other words, because each roller's axis of rotation is aligned to thesingle axis of potential rotation of each of the hone's hoofs thehorseshoe rollers can roll with and follow the annular rotationalturning movement of the horse's hoof about said hoofs single verticalaxis while resisting linear directions of rolling or slippage movementof a hoof along the surface of a pathway, while with said rotationalmovement of a horses hoofs said horseshoe rollers will ride up and rollover small obstacles on a pathway that an ordinary conventionalhorseshoe may snag upon.

No two Horses are exactly alike—and not even the hoofs of the same horsehave their vertical axis all respectively located at the same exactpoint of rotation of a hoof The point of the vertical axis of a hoof issubstantially located generally for all horse hoofs at the forward pointof cartilage space where inside a hoof the Navicular bone (distalsesamoid) meets the Coffin bone (Distal Phalanx). And this said axialpoint of actual rotation is different for each and every hoofaccordingly to the fine physical structuring of a particular horse—d aparticular hoof. Although the said differences of hoof axis is not greatit is important for the general well being of a horse shod withhorseshoes of this invention for rollers of said horseshoe to be able tofind and point to the location of each hoof axis of rotation to enable ahorse to rotate its hoofs as easily as possible as wild horses can withtheir bare hoofs romping on the plains and desert surfaces of naturalmother earth.

Therefor a particular feature of said horseshoes is that all rollers 73of FIGS. 21 and 22 are designed to automatically adjust their horizontalaxis of rotation to find and point to the single vertical axis ofrotation of a horses hoof by said rollers fluctuating their horizontalaxis of rotation about their vertical axis to find and follow a—of leastresistance coaxially around each hoofs said vertical axis below.

To assure long life of this horseshoe said rollers also automaticallyadjust themselves for wear of their bearing surfaces to maintain tightroller seals against invasion of significant amounts of dirt and gritparticles into interior spaces of the horseshoe.

All bearing surface parts of the horseshoe, including roller keeper sealflaps 79 are self-lubricating from the internal-lubricant of thematerial of which parts with bearing surfaces are made of and thereforeare maintenance free with said lubricant remaining within the physicalbounds of the bearing surface of the material of a part which saidinternal-lubricant is a bound component of.

Rollers 73, FIGS. 2I and 22 may be made from tungsten metal, of thelesser fragile type, to retain uniformly smooth contact bearing surfacesfor a long period of time which uniformly meet seal surfaces withoutopen spaces to maintain sealing of parts again internal invasion ofsignificant particles of dirt and grit as mentioned. But, too, in thisregard the horseshoe is designed to have rollers and other bearingsurface parts that when worn out can be quickly and easily removed andreplaced while the basic foundation of the main body 86 of thehorseshoe, that is designed to last much longer than its bearingsurfaced parts, remains in place on the hoof of the horse and thereforexceptionally long wearing rollers of tungsten are not necessarily acritical part nor necessarily the only choice for roller material andtherefor Metal Compound or Acetron NS rollers which are much less costlyto produce, are lightweight vibrate less and quieter in operation thantungsten, wear well and strong enough to replace steel may be preferablechoices.

FIG. 20 shows a side elevation schematic view of the horseshoe main body86 in particular reference thereof of this invention to a pointed toe 84region of the horseshoe integrally formed wit a toe riser 82 which saidriser projects upwards higher than the remainder of the horseshoe'shorizontal structural height and designed to butt against a complementalvertically flied right angled surface region 83 of the toe of the hoofwhich resists all backward shilling of said horseshoe. The said riser 82and its inclined front surface toe region which slopes downward to forman artificial pointed hoof toe region 84 are integrally secured regionsof the front end of the one piece horseshoe main body 36. Said pointedtoe front end 84 is designed to be an extension of the naturallyinclined sharply pointed form of the toe of the hoof which mother naturein her infinite wisdom designed for the fast running horse to keep thequick forward movement action of a hoof from being too often tooabruptly stopped on a soft surface the hoofs may dig into when a horseis romping or galloping about on soft earth to prevent stress injuriesto the complex structure of the horses lower legs and hoofs by providinga sharply inclined pointed hoof thus having the mechanical advantage todig in and push aside some of the said earth therefor more safelygradually dissipating and absorbing impact forces to the hoofs and legsof the horse to bring the horse to a gradually baited position. If saidhoofs were structured with blunt front surfaces the horse whenattempting to dig in at a surface with its hoofs when slowing down for aturn or coming to a complete stop from a running gate would under suchcircumstance either most likely slide rapidly in any direction or mostlikely forced to very abruptly dig in and causing the horse to come to acomplete sudden stop so abruptly that the horse's legs may fold under itby the over-riding force of the stored kinetic energy in the longhorizontal main body of the horse; and if not made therefor to fallcould strain and cause injury to its lower legs especially if such anaction is done repeatedly.

In FIGS. 21 and 22 structural elements and functions are disclosed ofthe horseshoe in more detail. As previously mentioned roller 73 canadjust its wiling direction to follow the orbit of rotation of a hoofaround its vertical axis to the extent of a back and forth twistingmovement of said roller revolving intermittently somewhat about itsvertical axis allowed within the confines of roller box 74 of whichinterior four straight walls of said box 74 have a widths greater thanthe length and diameter of said roller 73, but the surface of the arc ofthe interior wall rounded four corners 74A of said box 74 arecontiguously nearly within the same partial orbital path taken by thecorners of said roller 74 in twisting movements about its vertical axiswithin said confines of said roller box 74 as shown illustrated in FIG.21 with the interior boundary of said box 74, shown superimposed withbroken lines 74 where it can be seen that only the minute radii corneredge surfaces of rollers 73 touch the arced corner surfaces of rollerboxes 74 and also only the same ends of the slightly concave roilingsurface 79 of said rollers come into contact with the overhead surfaceSO of said roller boxes 73, which said bearing surfaces configurationallows a quickly started and efficient movement of said rollers havinglittle frictional resistance to overcome with benefit too of each ro'shorizontal axis of rotation automatically being exactly radially alignedto tract around with a hoofs rotational movement around its verticalaxis while each said roller has a little give in their coordinatedabilities to absorb shock by being able to be fated more deeply into thebody of said horseshoe and to twist somewhat about their vertical axeswhen striking nail obstacles to ride up and roll over on the pathways ofa horse; while with these said actions including said twisting movementsof said rollers which spread out bearing surface wear on roller boxes74, said corner bearing surfaces 74A which therefor increases the lifeof the more broad bearing surface areas of said roller boxes contactedby the sharply rounded small minute radii bearing surfaces of saidrollers thus constantly shifting points of contact to the much morebroad co-bearing surfaces of said corners and overhead of said rollerboxes 74.

In addition to the above said movement of rollers 73 within roller boxes74 said rollers also move Anther into the horseshoe main body 86 toabsorb the shock of applied force of some of the weight and/or strengthof a horse impacting said horseshoe rollers with each down-step againsta pathway's surface causing said rollers therefor in turn to forceroller box 74 overhead to press against resiliently compressible spring75 telescopically compressing the coil of said spring that is in apositional arrangement between the exterior surface of roller boxoverhead roofed roller box compartment 76 overhead surface which saidmovements of parts and compression of said spring thereby absorbs someof the shock of said rollers—said pathway surface.

Also, when said force of weight and/or strength of said horse isrelieved from a horseshoe roller box spring 75 the said spring expandsand pushes said roller box outwards to rest against resiliently flexibleseal layer 77 which seals off vent grooves 12 and 13 (below) and alsopushes roller outward more tightly against roller keeper seal flaps 77Aand which expansive force of said spring seal off vent grooves 12 and13, and keep flexibly resilient roller flaps 77A against rollers 73which provides quiet operation of a horseshoe by dampening soundvibration and keeping said movable parts from rattling around withinsaid horseshoe with stepping motions of a horse.

These said workings of the horseshoe also work to provide a ventilatorsystem feature of the horseshoe when as aforementioned said roller box74 moves more deeply into roller box compartment 37, therefor stale airand/or fluid rapped inside of horseshoe between said roller box 74 roofand interior walls of roller box compartment 87 are fated to flow out ofhorseshoe along roller box exterior wall vent groove 13 engaged to nowopened roller box compartment interior wall vent groove 12 along whichsaid air flow continues its journey out of horseshoe between roller 73and roller seal flaps 77A and also out between Y-slits at corners ofsaid roller boxes 74. And when the horse raises its shod hoof off of asurface and pressure is relieved off of a horseshoe and therefor off ofhorseshoe rollers 73, the said roller 73 and roller box 74 then mowoutward from roller box compartment 87 and therefor die said roller boxsucks some air back through vent grooves 12 and 13 and into air spacebeing created between said roller box 74 and roller box compartment 37as said roller box 74 continues to move outward until the bottomperimeter of said roller box 74 engages and is pressed against seallayer 77 by expansive force of spring 75 which action then blocks theouter opening of engaged vent grooves 12 and 13. And when the boastsshod hoof is again pressured against a surface said roller 73 againforces said roller box to move again more deeply into roller boxcompartment 87 and away from seal layer 77 which action unblocks outeropening of vent grooves 12 and 13 . . . and so it goes, keeping thehorseshoes ventilated and cooled with each stepping action of the horseslegs.

Each roller 73 is provided with a die-stamped resiliently flexible andpreferably internally lubricated said roller keeper seal flaps 77A thatare integrally connected to seal layer 77 FIGS. 21 and 22 that hasroller openings with corner V-slits at all four corners, as at 77B and77C, FIG. 21, that, as at 77C closely fit said seal layer 77 to thestraight flat sides of said rollers 73 and with movable V-slit 77Ballowing said rollers 73 to have small twisting motions about itsvertical axis with room thereof provided in roller box 74. The twomovable said roller keeper seal flaps 77A curl outward against sides ofeach roller's rolling surface which said flaps 77A follow said rollersmovements and keep significant amounts of dirt and grit from enteringinto the body of said horseshoe. All roller boxes 74 are preferably madeof the internally lubricated material ACETRON NS. All rollers 73 areprovided with said roller keeper seal flaps 77A that only lightly touchrollers slightly concave roller surface when said rollers are depressedinto the horseshoe body and therefor said flaps 77A only provide lightfrictional resistance to a rolling movement of said roller, thereforsaid flaps 77A bearing surfaces are expected to have a very long lift.Flaps 77A may as an option, be made of materials that although they maynot have an internal lubricating property have smooth low frictionsurfaces that resist abrasion and have a high tear strength such asUltrahigh-Molecular-Weight Polyethylene, or the material Millathane oranother material having the very desirable properties of being alightweight non-fatigue material having a high tear strength such asHytrel of a particular suitable type such as HTX-3177 a thermoplasticelastomer

The concave rolling surface of roller 73 shown in FIG. 21 is exaggeratedfor sake of illustration. Because the said roller surface is concave therollers ride bard on their sharply defined end rolling areas that tendto dig into soft ground surface, and have good traction on hard smoothsurfaces. Portions of the vertical flat sides of all rollers thatproject from the horseshoe become buried into soft ground with the saidvertical flat surface ends of each railer facing in a differentpositional arrangement in the horseshoe than of the positions in thehorseshoe of all other said rollers and therein provide excellenttraction footing for a bone. And when rollers 73 are on smooth hardsurfaces 37 rollers of a horseshoe which, as mentioned, are all facingin different directions from each other and bear all of the weight of ahorse on the sharp ends of their said concave roiling surfaces ride hardon smooth surfaces and grab onto any minute unevenness and/or roughfaults and gritty dirt present on all surfaces to provide excellentfooting for a horse. The infinite small amount of lubricant that mightbe picked up from the physically bound internally lubricated material ofa roller box 74 and roller keeper seal flaps 77A onto the bearingsurface of a roller is so snail that it posses no lubricant propertytransferable to a smooth footing surface from the horseshoe rollerssurface, in that all but a microscopic amount of lubricant might comeonto said rollers from said physically bound lubricated material of saidroller box 74 or said flaps 77A because such internally lubricatedmaterial is designed to lubricate itself m a manner that reduces thecoefficient of friction of the said internally lubricated parts surfacefor another part to ride on and bear against without passing asignificant amount of lubricant to said other part's bearing surface;such as for example the non-stick surfaces of Teflon coated food pansand pots having such a low coefficient of friction foods will not adhereor stick to the said Teflon surface and the said Teflon lubricatedsurface does not come off of the said pans and pots onto the food; andof which said Teflon material some maintenance free internallylubricated parts such as machine bearings are made of and Teflon is thenon transferable physically bound internal lubricant which in fact is apreferable choice for a solid lubricant that is available for theinternally lubricated material called Acetron NS of which said rollerboxes 74 are to be preferably made of. And Teflon or Graphite areoptional choices as the bound internal lubricants in the selflubricating material PTFE which may be the material of choice for thehorseshoe's seal layer 77 and its integral roller keeper seal flaps 77A.

When the main bearing surfaces of a roller 73 and/or roller box 74 andperhaps also roller keeper seal flaps 77A become worn and requirereplacement they are all easily expeditiously removed and then replacedhi and on the main body 86 of the horseshoe. First, if the said flaps77A also require replacement Said flaps as mentioned, are an integralpart of the one piece of flexible material layer 77 which covers most ofthe bottom surface of the horseshoe's main body 36 as does the bottomplate 94, cover most of the bottom surface of flexible material layer77, both of which are removed by first backing out but not removing allbottom plate screws 14. All said screws 14 are screwed through keyholetype screw holes in bottom plate with one side of said keyholes largerthan the heads of screws 14 therefor by simply having bottom plate 94turned face downward and tapped to cause said plate 94 to gravitatedownward against screw heads of screws 14 and said plate 94 then movedto one side to large hole side of said screw keyholes and said plate 94then removed from horseshoe past heads of said screws 14. Then saidflexible layer 77 is simply removed by peeling it off of said screwheads. All assemblies of a horseshoe roller?) roller box 74 and rollerbox spring 75 of the horseshoe main body 86 are now made accessible tobe lifted out or dumped out of the horseshoe. If the horseshoe is stillattached to the hoof of a horse a small sheet of five eights inch thickplywood can be placed under the horses hoof before disassembly of saidhorseshoe, and with said horseshoe disassembled with bottom coveringsoff with a hoof held up the said hoof is then allowed to drop onto saidplywood to dump all movable parts from the main body 86 of the horseshoeonto said plywood sheet and inspected, which parts are the roller 73.roller box 74 and conical spring 75. Said spring's smallest bottomhelical loop is either screwed or forced fitted into recessed springhole 92 of roller box overhead 80 for attachment to said roller box 74for expedient removal with removal of said roller box. And for simpleand expedient replacement of all hard said movable parts of horseshoemain body 86 still attached to the hoof of a horse may be used havingthe same perimeter profile as the profile of the horseshoe with openingsthrough the said jig of a form complemental in shape, size and spacingorientation of the horseshoe main bodies 86 roller box compartments 87positional arrangements, as at 87 FIG. 22. A flat thin slide sheet ofrigid material is included placed in a horizontal saw cut, cut throughall said roller box compartment 87 jig openings for roller box 74 whichsaid placement of flat thin slide sheet temporarily blocks the bottomopen regions of all said jig roller box compartment 87 shaped holes.Then new assemblies of a roller box 74 with attached spring 75 androller 73 are placed into each said jig openings and rest on said jigslide sheet Said jig has four attached downward projecting pegs employedto properly guide the position of said jigs horseshoe shaped perimeterto complementally match the perimeter form of the horseshoe's main body86 which positions said jig roller box assembly blocked openings to beexactly aligned to the roller box compartments openings of thehorseshoe's main body 86. With said jig placed onto the main body 36 ofa horseshoe attached to the uplifted hoof of a horse the said jig slideis then carefully removed from the jig allowing all said jig holeassemblies of roller box 74 and its attached spring 75 and roller 73 togravitate down together into all of the horseshoe's main body roller boxcompartments 87. Then either a new or the old flexible seal layer 77 isnow installed onto the horseshoe by correctly pushing flexible layer'sscrew 14 holes onto and snap-fit around all projecting screw heads ofscrews 14 in horseshoe's main body 86 which will position the rollerkeeper seal flaps all in place Stops of rollers 73 Next said thin bottomplate 94, the last layer of the horseshoe which protects and keeps inplace said flexible seal layer 77 and all flaps ha, is reassembled tothe horseshoe in reverse order of its disassembly therefrom with all ofthe small screws 89 now projecting out of said metal plate the sides ofsaid metal plate 94 and side of flexible layer 77 are aligned to andprotected at the inside projecting surface of perimeter lip 107 of saidhorseshoe main body 87, and then said screws 14 are all firmly screweddown in place onto said metal plate and thus said horseshoe is fillyassembled and refurbished and ready to be of service to the horse asdisclosed in the specification.

The said assembly of the horseshoe of this invention is approximately ofthe—manner of which the manual assembly of new horseshoe units may beconducted.

The said horseshoe may be supplied requiring assembly as disclosedabove, or may come already almost completely assembled as illustrated atleft side of drawing FIG. 22 with all small screws 14 extended outwardsthrough holes in layer 77 in ready positions for shodding the unit tothe hoof of a horse accept for units bottom plate 94 which would bepacked as a separate part with a horseshoe unit, but all small screws 89backed outwards into ready positions for installation of said bottomplate 94. The flexible layer 71 may be furnished as mentioned with holesin it somewhat larger than screw heads 90 to allow withdrawing partiallyassembled screws 91 through said flexible layer 77 for shodding thehorseshoe to a horses hoof without removal of said layer 77 as disclosedabove. Small screws 14 which remain partially screwed into the horseshoemain body 86 keep said layer 77 sufficiently enough in place to retainall parts shown within said main body 86 therefore simplifying shoeingof the horseshoe to the hoof of a horse also as disclosed above.

The horseshoe of this invention may be installed onto a horse in anymanner deemed practical such as aching to conventional horseshoesalready shod to a horse temporarily or reconsidered as permanentinstallations. Said horseshoe of this invention may be attached to ahorse via straps, or glued onto a hoof or attached to a horses boots andeven ached to a hoof as a horseshoe of this said invention in more thanone piece such as one separate piece for each side of a hoof which wouldbe another means to allow natural flexing of the hoof wall when thehorse is in motion; or complemental horseshoe fork end pieces of theflexible frog regions of a hoof separate from a contiguous third pieceof said horseshoe that is attached to the forward sides and toe of saidhoof or by any means of attachment that makes use of the inventivenessof the horseshoe's features including safety, agility and refurbishedlong life features of the horseshoe being within the scope of theinvention.
